Big Ben or Mahomes during Playoffs

So league mates and i were chatting about what Hunt’s release does for the offense as a whole, and several members felt that its gunna take passing pressure off opposing defenses as ware is much less of a passing play threat than hunt was, and that even PA plays are going to be less successful.

I’ve always liked having 2 qb on my roster, and have Big Ben as well as mahomes.
Question is, do you still consider Mahomes a must start now, or would you play Ben in a favourable matchup over Mahomes?
i.e. Ben has a seemingly favourable schedule during fantasy playoffs an Mahomes has a gauntlet.
